Vaillant is one of the big names in boiler manufacturing. But you might still be wondering whether they’re the right choice for your home. With so many companies now within the boiler market, it can be confusing to understand precisely what’s the best option for you, and importantly, how much does a new boiler cost.

In this guide, we’re going to take a look at some of the models from the Vaillant range.  We’ll take a look at combination, system and regular boilers and then provide you with a complete list of all the current models along with information on what you can expect to pay.

Vaillant Combi Boilers Prices From £770 to £1,481

Combination boilers are the most popular heating choice for UK households. Their quick production of hot water without the need for additional tanks makes them an efficient and space-saving option.

Vaillant ecoTEC exclusive with Green iQ From £1,267

Vaillant considers the ecoTEC exclusive as being the very best in the business. With a strong focus on energy efficiency, it means the lowest levels of fuel consumption and, in turn, low running costs. The eco-credentials also extend to the manufacturing process, and that’s because once the ecoTEC comes to the end of its working life, 85% of its components can be recycled.

The boiler is compatible with Vaillant’s vSMART control system, which gives you complete control over your heating via your smartphone or tablet. But, even when you’re not keeping an eye on what’s happening, the ecoTEC adapts itself so that you get exactly the heating that you want. So, yet again, Vaillant has found a way to allow their boilers to waste less energy and to reduce your fuel bills.

This boiler is available with two different power outputs, 35kW and 43kW, which can provide 17.8 litres of hot water per minute. As you would expect, this is an ErP ‘A’ rated boiler, and if you’re not on a mains gas supply, then the ecoTEC can also run on LPG.

Vaillant ecoTEC Combi Store From £1,386

vaillant boiler prices

Larger homes often have the need for high volumes of hot water. The challenge then comes from when more than one shower is in use at the same time or when you need hot water in the kitchen when someone else is running a bath. These are the times when a traditional combination boiler can struggle to meet those demands.

Traditionally, the solution has been to fit a regular or system boiler. However, this also needs a hot water cylinder and the addition of a cold-water tank in the case of the regular boiler. The ecoTEC plus 38kW combination store now provides the convenience and efficiency of a combi boiler, with the high-volume hot water supply of the system boiler.  The ecoTEC is able to deliver 20 litres of hot water per minute, much more than your standard combination boiler.

For many households, though, there are only certain times of the day when they need that high volume of hot water. So, away from those times, the ecoTEC drops to using just 16% of its maximum power to provide savings on fuel and money. As with many of the Vaillant models, the ecoTEC is super quiet when operating and, as such, has been awarded Quiet Mark accreditation.

  • Stay in control when you’re away – simply tell the app that you’re heading out for a few days, and it will balance frost protection with unnecessary heating of your home.   
  • Change with the season – the app is able to monitor local weather conditions and then adjust the boiler to the perfect temperature. All without you needing to think about it!

Vaillant Regular Boilers Prices

When a regular boiler comes to the end of its working life, then the most straightforward option is usually to replace it with one of the same type. Though the choice of regular boilers is a little more limited, Vaillant provides a wide range of power outputs across the two models on offer. Vaillant regular boilers require the use of both a hot water cylinder and a cold water tank, which is usually in the loft.

ecoTEC Plus Regular Gas Boiler £679

This is a compact, kitchen cupboard sized model that’s become well known for its reliability. There are six different power outputs on offer ranging from 12 right through to 35kW, meaning that the ecoTEC Plus is going to be suitable for most sizes of homes. When that’s combined with its efficiency level and ease of use, then it’s easy to see why this is such a popular model.

Vaillant System Boilers Prices

If you want a Vaillant boiler but you are unsure if a combi boiler can keep up to your household water demand, then you need to consider a system boiler. If you already have a hot water tank or cylinder in your home then a simple system boiler swap would be perfect. If you don’t have a hot water cylinder already then this will be an extra cost on top of the boiler unit itself. Always check what type of boiler you currently have as changing your boiler type can be expensive.

Vaillant ecoTEC Pure System Boiler From £738

When there’s little spare space, the ecoFIT Pure comes to the rescue! That’s because its compact design means that it can fit into a standard kitchen cupboard. It’s also been designed with a choice of flue options to provide even more flexibility for where it can be installed.  

The small size doesn’t, though, mean that this isn’t a boiler packed with features. The powerful aluminium heat exchanger, for example, offers fantastic performance resulting in low energy consumption. And that theme continues with its smart operations, whereby it can switch to just 20% of its maximum output when demand for hot water drops. 

Valliant has also considered how they can protect the heat exchanger and extend its reliability, and they’ve done this by installed a 4-sided cooling and water agitation system.  Stress on the heat exchanger is reduced, and maintenance requirements are minimal.

Who is Vaillant?

vaillant boilers prices

It was 1874 when Vaillant was established in Remscheid, Germany and twenty years later, they launched their very first gas boiler. In 1967 they launched the ‘Combi-Geyser’ that allowed both hot water and heating to be generated from the same unit. This was the forerunner for the combination boiler that we’re now so familiar with.

Throughout its history, Vaillant has had a strong focus on innovation. From being the designers of the world’s first fully mixing atmospheric burner to being the first UK boiler manufacturer to be awarded Quiet Mark accreditation.

Vaillant UK has its award-winning factory, at its Derbyshire headquarters in Belper. In addition, they have a team of over 250 engineers based across the country and the largest renewables service fleet of any of the boiler manufacturers within the UK

Vaillant Boiler Warranties

Vaillant offers some generous guarantee periods on their range of boilers but to get the maximum length of cover, you do need to ensure that you meet all of their requirements. When this hasn’t happened, you may find your ten-year warranty slide right down to just twenty-four months.

There are thirty-one different clauses in the Vaillant terms and conditions relating to their guarantees, but we’ve picked five critical elements for you:

  1. A Gas Safe registered engineer must install your boiler, and that needs to happen within six months of the boiler being sent to you from the Vaillant warehouse.
  2. Once the installation is complete, the engineer must complete the Benchmark logbook. Vaillant may ask to see this if you call them out during the warranty period, so it’s essential to keep this somewhere safe.
  3. You also need to keep proof of purchase to ensure that the warranty commences from install rather than the date of manufacture.
  4. Once the boiler has been installed, the guarantee must be registered with Vaillant within a 30 day period.
  5.  Servicing must take place every year and be completed by either a Vaillant or Gas Safe Registered engineer.
